Editorial Changes to Align with 262 (#120)

* upgrading ecmarkup
* preparing the spec to rename internal slots to start with uppercase character. this change allows a clear separation between internal slot names and properties/fields used across the spec as in [[<name>]]. This change does not change any semantic or any logic, it only adds internal slot column in table 4 and table 2 to have a clear distintion between property and internal slot names.
* editorial: alignment with 262 by naming all internal slots to start with uppercase characters. This change does not change any semantic or any logic.

         Unicode Technical Standard 35 describes ten locale extension keys that are relevant to collation: "co" for collator usage and specializations, "ka" for alternate handling, "kb" for backward second level weight, "kc" for case level, "kn" for numeric, "kh" for hiragana quaternary, "kk" for normalization, "kf" for case first, "kr" for reordering, "ks" for collation strength, and "vt" for variable top. Collator, however, requires that the usage is specified through the usage property of the options object, alternate handling through the ignorePunctuation property of the options object, and case level and the strength through the sensitivity property of the options object. The "co" key in the language tag is supported only for collator specializations, and the keys "kb", "kh", "kk", "kr", and "vt" are not allowed in this version of the Internationalization API. Support for the remaining keys is implementation dependent.
